Further informationRemember that humans are not built the same way as birds, and so we cannot fly – not even if we dress up in feathers or try to build ourselves a pair of “wings.” Flying is unique to birds only, so leave this special trick for the experts to handle!
ExplorationWinged wonders!Did you know that there are some birds who actually aren’t able to fly? Two really good examples include penguins and ostriches!A big reason why both of these birds don’t fly is that they’re heavier than most other birds. However, they do still use their wings! Penguins rely on their wings for helping them propel through water, and ostriches use them for balance while running!
